CUBEISM

"LeWitt first chose to work with the cube in the 1960s because he found it the 'least emotive' three dimensional form; he chose white 'because it was less expressive than black.' Nevertheless, both the cube and white do have powerful emotional resonances and expressive effects. LeWitt was not indifferent to this, having observed that 'Three-dimensional art of any kind is a physical fact. This physicality is its most obvious expressive content.'"
